The answer to the equation is 4.
Answer:
RS = 6
Step-by-step explanation:
RS² = SU*ST (secant-tangent rule)
Substitute
(x + 6)² = (x + 4 + 5)(x + 4)
(x + 6)(x + 6) = (x + 9)(x + 4)
x(x + 6) +6(x + 6) = x(x + 4) + 9(x + 4)
x² + 6x + 6x + 36 = x² + 4x + 9x + 36
x² + 12x + 36 = x² + 13x + 36
Collect like terms
x² - x² + 12x - 13x = -36 + 36
-x = 0
x = 0
✔️RS = x + 6
Plug in the value of x
RS = 0 + 6
RS = 6
I think it can be 605. I'm not sure exactly, but I think it is.
Hey there!!
- The area of a circle = πr²
The area is given as 196π
Hence,
196π = πr²
... r²= 196
... r = √196
... r = 14
<em>Hence, the radius is 14 cm. </em>
<em>Hope it helps!</em>
